Installation and Upgrades / LDAP Permissions

« on: October 06, 2014, 10:58:31 am »

Hi,

I need to give a NON-Admin permissions to add users / and modify groups. He should not be able to modify Users.

Is that possible somehow. Maybe through an LDAP-Explorer...?

Anyone?

Thanks!

Installation and Upgrades / slapd[4551]: warning: cannot open /etc/hosts.allow: Too many open files

« on: February 12, 2014, 01:54:34 pm »

Dear all,

our ldap (slave, zentyal 2.2) stops working because of

Code: [Select]

slapd[4551]: warning: cannot open /etc/hosts.allow: Too many open files

I increased limits:

Code: [Select]

less /etc/security/limits.conf
...
root             soft    nofile          65536
root             hard    nofile          65536
openldap         soft    nofile          65536
openldap         hard    nofile          65536
*                soft    nofile          65536
*                hard    nofile          65536

and

Code: [Select]

less /etc/sysctl.conf
...
fs.file-max = 120000

which looks quite ok:

Code: [Select]

ulimit -a
...
open files (-n) 65536

BUT slapd still only uses 1024...

Code: [Select]

cat /proc/"slapdID"/limits
...
Max open files            1024                 1024                 files   

Any ideas?

Thanks!

Installation and Upgrades / Microsoft Exchange replacement

« on: October 18, 2013, 02:36:21 pm »

Hi zentyal-devs,

I just read http://www.zentyal.org/2013/10/zentyal-launches-the-only-native-microsoft-exchange-replacement/ - great news.

Did you consider integrating SOGo (http://www.sogo.nu) as well? Its working very well with zentyal (using it with zentyal since zentyal 2.0) and its using OpenChange for native Exchange-connectivity as well.

Might be a good match!

Best regards
Steve

Installation and Upgrades / nf_queue: full at 1024 entries, dropping packets(s).

« on: February 06, 2013, 09:59:20 am »

Hi all,

we are using zentyal 2.2 as gateway without problems so far. But suddenly our gateway (8GB Ram, Intel® Xeon® E3-1230 3,20GHz - updated to the latest software versions) shows the following messages in syslog

nf_queue: full at 1024 entries, dropping packets(s).

It seems the l7-filter is too slow, queue is full and droping packages - result is no or very slow internet-acces. We just have one traffic-shaping rule for VOIP, which was running OK the last 6 month. Our network hasnt changed lately, so we really dont know why these problems occur now.

Any ideas?

Thanks!

Installation and Upgrades / ejabbered: shared roster with zentyal 2.2

« on: December 20, 2012, 04:52:10 pm »

Hi all,

I´ve seen that shared roster for ejabbered is available for 3.0? Any chance to use that feature with 2.2 as well (changing configuration manually)?

Thanks!

Installation and Upgrades / default email adress

« on: March 07, 2012, 03:41:17 pm »

Hi all,

another short question. Zentyal creates automatically an email-account for new users with mail-adress "userid@mydomain.com".
Is it possible to change that somewhere to "firstname.lastname@mydomain.com" if this is not taken and userid@mydomain.com only as fallback?

Thanks!

Installation and Upgrades / multigateway weight

« on: March 05, 2012, 02:34:27 pm »

Dear all,

quick question for a multigateway setup: I want to use one ADSL (16000kbit down/1024kbit up) line togehter with a symmetric 10000kbit (10000up and down) line. How to manage these to lines in a zentyal mulitgateway setup (I want to use both lines in parallel)?

There is only one parameter for weight - but I have different speed ratios in download / upload... how to solve this?

Thanks
Steve

Installation and Upgrades / [SOLVED] mailfilter error after update to 2.2

« on: March 05, 2012, 09:31:29 am »

Dear all,

we just migrated our mailserver from zentyal 2.0 to zentyal 2.2 (it´s a zentyal slave). Everything works fine, expect the mailfilter module. When I enable it it shows the follwing error after saving:

Code: [Select]

Some modules reported error when saving changes . More information on the logs in /var/log/zentyal/
The following modules failed while saving their changes, their state is unknown: mailfilter
zentyal.log does contain the following error:

Installation and Upgrades / Zentyal 2.0 -> 2.2 Update Error (Master/Slave)

« on: December 30, 2011, 10:08:58 am »

Hi all,

I tried to update our master/slave setup with the provided migration-script. On master all went well but unfortunately on both slaves the update failed. Some details:

After updating all packages I checked if everything is still ok - it was, so I went on with the update. The update failed during configuring zentyal-core - I searched the forums and found: http://forum.zentyal.org/index.php?topic=8818.0
It seems I have the same problem, since

Code: [Select]

usermod --home /var/lib/zentyal/ ebox throws the error that "user ebox is currently logged in".

It seems some users are affected by this problem (http://forum.zentyal.org/index.php/topic,8818.msg37619.html#msg37619) - any workarounds / tips?

Thanks!
Steve

Installation and Upgrades / Possible to add a custom ldap schema?

« on: November 24, 2011, 08:57:51 pm »

Hi all,

we are using zentyal in a master-slave setup together with sogo. Everything works great - thanks a lot for zentyal!

SOGo is able to handle resources (meeting rooms, ...) but needs an extra ldap schema for this. Is it save to add this schema (http://wiki.sogo.nu/ResourceConfiguration?action=AttachFile&do=view&target=calresource.schema) to our slave where mail-service and SOGo is running, or is this generally a bad idea?

Thanks,
Steve

Installation and Upgrades / password length/age without pdc?

« on: April 01, 2011, 11:34:35 am »

Hi all,

we are using zentyal in a master/slave setup but we dont use it as PDC.

Is it still somehow possible to define values for password length/age which are used at the user-corner on the master-server? When I set values at the samba-slave (PDC) the user-corner is not affected, e.g. it es still possible to use very short passwords.

Thanks!
Steve

Installation and Upgrades / Reboot -> Connection to zentyal internal mail-filter denied

« on: February 07, 2011, 02:25:51 pm »

Hi all,

I have a slave working with mail and internal mailfilter configured. Everything is working smoothly, but when I reboot the slave all mail is queued because the access to the internal mailfilter is denied.

When I restart (disable/enable) mailfilter everything works again. Is this a bug? How can I ensure that evrything works after a reboot without manually restarting mailfilter?

Thanks for any help!
Using newest zentyal on ubuntu 10.04

Best,

Installation and Upgrades / [SOLVED] Master-Slave: Ldap confusion

« on: January 11, 2011, 11:34:30 am »

Hi all,

I have some problems understanding the zentyal ldap configuration when using master-slave setup. maybe someone can give me some insights...

I have a thrid party app (on a different server) which works fine using the master-ldap for authentication - but I am missing the user-mail-informations. Since the third party app needs mail-information from ldap I try to use the slave ldap where mail-services are running.

I undestood that a slave Zentyal server has three LDAP instances (frontend, translucent and replica). I am able to connect to frontend on port 389 and replica on port 1389, but none is working for authentication (using the same config which is working fine for the zentyal master).
 
I checked with a ldap-browser (ldap browser and apache directory studio) and neither frontend nor replica are showing the complete ldap tree. Unfortunately I cannot connect to translucent on port 1390. Is the port blocked by the zentyal firewall (I allowed access to ldap)?

So any chance to have access to a complete ldap tree on a slave and use that for authentication?

Thanks for any hints,
Steve

Installation and Upgrades / Zarafa email-adress setup somehow possible (prof. support)?

« on: January 06, 2011, 01:56:29 pm »

Hi everyone, zentyal-staff,

i just evaluated zentyal for my company and convinced everybody to give it a shot. One requirement from my company is to use zarafa and short zentyal login-names BUT name.surname for email-adresses.

As discussed in other posts (e.g. http://forum.zentyal.org/index.php?topic=5247.0) the  following seems not to be possible to setup with zentyal&zarafa (using roundcube works fine):

Username: short
Email: surname.name@domain.com <- use for send and receive in zarafa
Alias: short@domain.com <- use only for receive in zarafa

I tried many approaches with no luck. Since i dont want to buy prof. support just to get the answer "sorry not possible" maybe a zentyal could just state "possible or not"?!?

Thanks!
Steve
